ENZYME entry: EC 2.1.1.204

Accepted Name
tRNA (cytosine(38)-C(5))-methyltransferase.
Reaction catalysed
S-adenosyl-L-methionine + cytosine(38) in tRNA <=> S-adenosyl-L-homocysteine + 5-methylcytosine(38) in tRNA
Comment(s)
  • The eukaryotic enzyme catalyzes methylation of cytosine(38) in the anti-codon loop of tRNA(Asp)(GTC), tRNA(Val)(AAC) and tRNA(Gly)(GCC).
  • Methylation by Dnmt2 protects tRNAs against stress-induced cleavage by ribonuclease.
  • Formerly EC 2.1.1.29.
